I am reporting the same bug I reported several months ago, for iptables 
1.1.1.

When compiling iptables/ip6tables with BINDIR, LIBDIR, etc. variables 
set to anything else than /usr/local/..., ip6tables doesn't work. For 
instance, a simple command like:

ip6tables -A FORWARD -j ACCEPT
doesn't work.

I have been able to trace the problem down to the fact that IP6T_LIB_DIR 
not being defined in the source code when compiling ip6tables, so it 
defines the default /usr/local/lib/iptables. That means that when 
installing the extension modules in, for instance, /usr/lib/iptables, 
the ip6tables program will break because it can't find them.

The solution is quite simple, actually. In the top level Makefile, the 
ip6tables compilation command-line defines IPT_LIB_DIR, when it should 
define IP6T_LIB_DIR. That solves the problem.

Here's the patch:
